UMBRELLA.

Application filed December 30, 1919.

To all whom it may concern:

Be it known that we, WALTER EMMETT AIREY and JOHN POMFRET, subjects of the King of Great Britain and Ireland, residing, respectively, at Copper Beeches, Fog Lane, Didsbury, Manchester, in the county of Lancaster, England, and 44; Greenhill road, Manchester, aforesaid, have invented new and useful Improvements in Umbrellas, of which the following is a specification.

The invention relates to improved means for preventing waterlogging, and for securing means for ventilation, in and about the top notch and outer ferrule cover of umbrellas, to prevent the premature d1s1ntegrat1on, rotting, and wearing of umbrella covers at this point. This premature disintegration, wearing and rotting is caused by the fabric at this part becoming waterlogged, as gen-- erally the umbrella is left standing when wet, and the water gravitates to th1s end of the cover, and owing to its being so closely folded at this part, air has no chance to act upon it to dry it quickly.

Our object is to construct and mount the top notch and outer ferrule in such a manner as will provide holes, channels or passages to allow for the rapid drainage of the water, such passages also providing means to 1nsure a free air circulation to the wet fabrlc to assist in promptly drying same. This we do by providing the top notch or barrel with internal and external longitudinal grooves, recesses or channels. We also provide the outer ferrule with drainage holes to allow for the drainage of the water.

The invention, which we will describe in detail, is illustrated in the accompanying drawings, in which, 7

Figure 1 is a sectional elevation of the improved umbrella fitting.

Fig. 2 is a plan thereof, and,

Figs. 3 and 4: show in plan and elevation respectively a modification of the fitting.

In carrying our invention into effect we form the top notch and barrel a, as usual, separate from the outer ferrule, the umbrella ribs being secured at a. The top notch and barrel a is made a tight fit upon the umbrella stick Z) which is shown in dotted lines. The top notch and barrel a is formed internally with longitudinal recesses'c and is provided with slits d from the bottom a short distance upward, and 1s screw threaded externally. On this top notch and Specification of Letters Patent.

barrel a is screwed the outer ferrule e the end of the ferrule having holes 6' bored therein. The outer ferrule e'is made at the bottom a tight fit upon the umbrella stick. ater entering the interior of the top notch a will drain down the channels or recesses 0 into the outer ferrule e and away through the holes e, Also water can drain away between the top notch a and outer ferrule e alongthe channels or grooves d, through the slits d, and out through the holes 6. This allows for the prompt drainage of the cover when wet, but also such channels or recesses, and holes, provide means for air to circulate and have access to the cover and insure its being dried quickly.

The Figs. 3 and 4 show a variation of the constructions already described.

In this arrangement the top notch or barrel a is formed with internal ribs (4 which produce longitudinal channels or grooves and with longitudinal external grooves of. The top notch or barrel in this instance is not screw threaded, the top notch, and the surrounding outer ferrule 6 being each secured to the umbrella stick by any convenient means. The internal ribs a and external grooves a produce longitudinal channels which permit of the drainage of water internally and externally from the top notch or barrel a into the outer ferrule e which is drained by means of the holes 6 as described;

/Ve declare that what we claim is:

1. In an umbrella, a notch provided at its interior with a plurality of longitudinal channels, and a ferrule encircling said notch and having radial openings communicating with the interior of the ferrule, said longitudinal channels of the notch also communicating with the interior of the ferrule.

2. In an umbrella, a notch provided at its interior with a plurality of longitudinal channels, and also provided with a plurality of radial slots, said notch bein exteriorly threaded for a portion of its length, and an interiorly threaded ferrule secured to said notch and provided with a plurality of radial openings, the longitudinal channels and radial slots of the notch communieating with the interior of the ferrule.

In testimony whereof we have signed our names to this specification.
